HEATING APPARATUS FOR METALLIC TIRES.

Specification of Letters Patent.

Application filed April 9, 1913.

Paton t ed July 8, 19.1.3.

Serial No. 760,007.

To all whom it may concern Be it known that I, VVILLIAM I-I. W'ALKER, a citizen of the United States, residing at Somerset, in the county of Perry and State of Ohio, have invented certain new and useful Improvements in Heating Apparatus for Metallic Tires, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to an improved heating apparatus for metallic wheel tires and has for its primary object to produce a heater wherein gas is utilized as a fuel, said heater including a plurality of adjustable jet pipes whereby tires of various diameters may be heated.

Another and more specific feature of the invention resides in the provision of improved means for mounting the heating pipes whereby they may be readily adjusted, as desired.

A further object of the invention is to produce an apparatus of the above character which is comparatively simple in its construction as well as durable and efficient in practical use and capable of manufacture at small. cost.

Vith the above and other objects in view the invention consists in the novel features of construction and the combination and arrangement of the parts to be hereinafter more fully described, pointed out in the claim and shown in the drawings,in which-- Figure 1 is a side elevation of a tire heating apparatus embodying the present invention, the inclosing metallic wall being shown in section; Fig. 2 is a top plan View thereof, the cover being removed; Fig. 3 is an enlarged section taken on the line 3-3 of Fig. 2; I! 4: is a section taken on the line 4t4t of Fig. 2; Fig. 5 is a detail perspective View of a portion of one of the heating pipes.

Referring in detail to the drawings, 5 designates two metal rings, which are arranged in superposed spaced relation, as shown. An inclosing metal wall, indicated at 6, is arranged in spaced concentric relation to these rings and to the inner surface of this wall the pairs of supporting bars 7 are riveted or otherwise securely fixed. The inner ends of the bars of each pair are similarly Additional single connecting bars 8 have their inner ends disposed between the spaced rings 5 and riveted or bolted thereto and are secured at their outer ends to the inclosing wall (5.

Supporting bars or legs 9 secured to the floor or a suitable base have their upper ends inwardly extended, as indicated at 10, beneath the lowermost ring 5. These inner ends of the bars 9 are provided with spaced openings to receive the lower ends of the clip bolts 11 which extend over and embrace the superposed rings 5,suitable clamplug nuts being threaded upon the extremities of said bolts.

12. designates a plurality of heating pipes which are of arcuate form in plan, as shown in Fig. 2, and are supported upon the radially disposed bars 8 and extend between the pairs of bars 7. These pipes are closed at their opposite ends and are provided in their upper portions with jet openings 13. Each of the arcnate pipes 12 is centrally provided with a T-shaped "anion 14, having a nipple to which one end of the flexible hose 1:") is connected. A cruciform head or conduit 16 is arranged below the metal rings 5 and to each branch thereof, the lower end of one of the tubes is connected, each branch of said head being also provided 'with a cock 17 whereby the supply of gas to each of the pipes 12 may be controlled independently of the remaining pipes.

Inwardly extending radially disposed bars 18 are connected at their outer ends to the several jet pipes 12 by means of the clip bolts 19, and the inner ends of these radial bars extend loosely between the spaced superposed metal rings 5. To the upper edge of the annular metal inelosing wall (3 at one side thereof, a sheet metal cover plate 20 is hinged. The supply head 16 is of course connected by means of a pipe 21 to the gas main and this pipe is provided with a valve 22 whereby the supply of gas to the distributing head may be regulated, as desired. Having above described the construction of my improved apparatus, its operation will be understood as follows :The tire T to be heated is arranged within the inclosing wall 6 and rests upon the upper radially disposed brace bars 7. The several gas pipes 12 are now adjusted by moving the same inwardly or outwardly with respect to the rings 5 so as to dispose the jet openings of said pipes immediately beneath the tire.

The gas is now turned on into each of the pipes 12 and the same ignited as it is used from the jet openings 13. The lid or cover 520 is then closed. It will be obvious that by providing the several independently adjustable heating pipes, substantially all portions of the tire will be heated to the same degree. Thus there will be equal expansion of the tire at all points so that the same can be properly shrunk upon the telly of a wheel when the tire is cooled.

By arranging the heating pipes, as shown, the consumption of gas necessary to heat the tires to a proper degree is reduced to a minimum, thus conducing to economy in the use of the apparatus. It will also be apparent that as the invention comprises but few elements in its construction, which are all of simple form, the same can be produced at small best. The device is also of great convenience and serviceability and provides means whereby the tire may be properly heated and shrunk upon the wheel with a material saving of time and labor.

Vhile I have shown and described the preferred construction and arrangement of the several elements, it will be obvious that theinvention is susceptible of considerable modification without departing from its essential features or sacrificing any of the advantages thereof.

What I claim is A device of the character described com prising spaced superposed guide members, an annular inclosing wall arranged in spaced concentric relation to said guide members, brace bars fixed to said wall at their outer ends and secured between the guide members at their inner ends, additional tire supporting bars secured to the upper guide member and to said annular wall, a plurality of heating pipes supported upon the first named brace bars, a bar fixed to each of said pipes and extending inwardly between the guide members, said latter bars and the brace bars supporting the heating pipes for radial and circumferential movement with relation to the guide members, a gas supply head, and flexible connections between the heating pipes and said supply head.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
